I Kennedy/Jenks Consultants i 6. Collect soil samples for lithologic logging purposes with a CME continuous coring system in 5-foot increments. 7. Collect soil samples for lithologic logging and chemical and physical analyses by driving a split- spoon drive sampler, in 2.5- to 5-foot increments, below the depth of the auger bit with a rig-mounted hammer. Record the standard penetration resistance. If the sample is pushed i rather than driven, be sure to record the push force. 8. Have the soils classified in the field in approximate accordance with the visual-manual T� procedure of the Unified Soil Classification System (ASTM D-2488-90) and the Munsell Color Classification. 9. Prior to each sampling event, wash the split-spoon drive sampler and brass liners with high purity phosphate-free soap, and rinse them with potable water. 10. At each sampling interval, collect soil in one brass liner for potential laboratory analysis. Cover this sample in Teflon sheets, seal it with plastic caps, and wrap it with silicon tape. Place a completed sample label on the brass liner. Then see that the samples are placed in appropriate l containers and stored at approximately 4°C. t 11. Complete chain-of-custody forms in the field and transport the samples in insulated containers, n at an internal temperature of approximately 4 °C, to the selected laboratory. J 1.4 Equipment Cleaning 1. Prior to drilling each boring, steamclean downhole equipment (augers, well casing, sampler). 2. Before collection of each drilling sample, wash sampling equipment (sampler and brass liners) with a brush, in a solution of high purity phosphate-free soap and potable water. Rinse the equipment with potable water. 3. Before leaving the site at completion of drilling, steamclean downhole equipment and vehicles that require cleaning. 1.5 Investigation-Derived Residuals cJ Place soil cuttings and other residuals in appropriately labeled containers for disposition by the client. All soil samples transported to the laboratory must be returned to the client for disposition. Kennedy/Jenks Consultants is available to assist the client with options for disposition of residuals.
